Soiling-Induced Efficiency Losses in Photovoltaic Systems: A Comparative Study of Monocrystalline Monofacial and Bifacial Panels

Dust accumulation on photovoltaic (PV) modules significantly impacts their efficiency and energy output, particularly in regions with high particulate deposition. This study investigates the performance degradation of monocrystalline Monofacial and bifacial PV panels due to natural dust accumulation over time. Experimental analysis was conducted at the Indian Institute of Technology Bhilai, where key electrical parameters such as power output and efficiency were monitored under clean and dusty conditions. Study indicates the losses observed in panels. This study helped determine and understand dusting patterns, with consistent decrease in power throughout experimental period. Additionally, adverse weather conditions caused significant performance fluctuations. The study highlights the necessity of optimized cleaning schedules, with monocrystalline panels requiring more frequent maintenance than bifacial panels. These findings provide valuable insights into dust mitigation strategies and system optimization for PV installations in dust-prone environments.
